The aim of this paper was to study the effect and mechanism of alcohol extract from Polygonum cuspidatum(PCE) on acute gouty arthritis in C57 BL/6 mice through NLRP3/ASC/caspase-1 axis. The model mice which injected with ankle joint injection of sodium urate crystals(MSU) were orally administrated with three different concentration of PCE, with colchicine as positive control. HE staining was used for observing the morphological changes of synovial tissue; concentration of IL-1β, IL-6 and TNF-α secreted by synovial tissue of the ankle joint were detected by ELISA; mRNA and protein expression of NLRP3, ASC and caspase-1 in synovial tissue were detected by RT-PCR and Western blot respectively. The results showed that the swelling degree of ankle joint in model mice were significantly elevated; expression of IL-1β, IL-6 and TNF-α were significantly increased; mRNA and protein expression of NLRP3, ASC and caspase-1 also significant increase, compared with normal control group. The swelling degree of ankle joint significantly relief; expression of IL-1β, IL-6 and TNF-α in joint synovium significantly decrease; mRNA and protein expression of NLRP3, ASC and caspase-1 were significantly decrease in PCE treatment group compared with model group. Our research implied that alcohol extract from P. cuspidatum had positive effect on acute gouty arthritis in mice, and the regulation of NLRP3/ASC/caspase-1 axis may be its mechanism.

The study aimed to determine if virtual reality (VR) games could enhance neuromuscular control and improve anticipatory and compensatory strategies in ball-kicking for soccer players. It was a single-blind randomized clinical trial involving 32 male soccer players with chronic ankle instability. Participants were divided into two groups: VR games and balance training.

Background: Female soccer athletes with a history of anterior cruciate ligament injury are more susceptible to secondary injuries and potentially worse sport performance. The purpose of this study was to determine if female soccer athletes post anterior cruciate ligament reconstruction demonstrate worse jump height and reactive strength index performance and lower involved limb hip, knee, and ankle joint power and absorption, and larger joint power and absorption asymmetries compared to matched uninjured athletes.
Methods: Eleven Division I female soccer athletes post anterior cruciate ligament reconstruction (18.

Rheumatoid arthritis is an autoimmune disorder affecting multiple joints and requires lifelong treatment. Present study was designed to formulate Esculin-loaded chitosan nanoparticles (ENPs) and evaluation of its anti-inflammatory and anti-arthritic action. The acute toxicity study of ENPs was also performed.

Purpose: Achieving precise postoperative alignment is critical for the long-term success of total knee arthroplasty (TKA). Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical in the early postoperative period. Supine computed tomography scanogram (CTS) offers a potential alternative.

The role of the human ankle joint in activities of daily living, including walking, maintaining balance, and participating in sports, is of paramount importance. Ankle joint dorsiflexion and plantarflexion functionalities mainly account for ground clearance and propulsion power generation during locomotion tasks, where those functionalities are driven by the contraction of ankle joint skeleton muscles. Studies of corresponding muscle contractility during ankle dynamic functions will facilitate us to better understand the joint torque/power generation mechanism, better diagnose potential muscular disorders on the ankle joint, or better develop wearable assistive/rehabilitative robotic devices that assist in community ambulation.
